Here in the UK many of the desk lamps I can buy nowadays take a bulb with
an Ediscon Screw fitting. Also many wall lights for outdoor use
(sometimes with a PIR detector) take an ES fitting bulb.

Try and avoid them.

Thanks for your opinion - is there any reasoning behind it?

Yes.

Until recently all I ever needed for a general purpose light bulb was a
bayonet fitting. Now ES fittings seem to be appearing! Pictures:

Is there a particular advantage of the ES fitting over the bayonet
fitting in these sorts of applications?

No, they are not as good as bayonet fittings.

Yes.
